modify crt0.c file

[Pask]

Hi i have the following problem:

i have added a call function in the crt0.c before the main call

init_FPB();
main();

i include my file .h (that contains the body of the function init_FPB) in the crt0.c file and so works.

but if I want to specify the body of the function in a file .c and leave only his signature in the. h does not work why?
I included file .c in the project but doesnt work.

You should not modify the crt0.c, do things in main.c.

Giovanni i need to modify it because i need some operation before main() function. Can you help me pls?

[Giovanni]

You may use an initializer function, see the GCC documentation, or use __late_init() in board.c.
